Question

A swimming pool of length 10 m and height 6 $\frac{1}{2}$ m can contain 5,20,000 litres of water. What is the breadth of the swimming pool?

Answer 1

Volume = 5,20,000 litres

1000 litres = 1 cubic metre

$\text{5,20,000}litres=\frac{520000}{1000}=520cubicmetres$ (1 marks)

Given:

length= 10 m

height = 6 $\frac{1}{2}$ =$\frac{13}{2}$ m

$\text{V= length}\times \text{breadth}\times \text{height}$

$\text{520= 10}\times \text{breadth}\times \frac{13}{2}$

$\text{520= 10}\times \text{breadth}\times \frac{13}{2}$

$\text{520= 65}\times \text{breadth}$

$\text{breadth=}\frac{520}{65}=8m$ (1 marks)
